208414, 208415 REPLACEMENT POWER SUPPLY KIT FOR ELECTRONIC AIR CLEANER

Modification To Reduce Ozone Odor

WARNING
ELECTRIC SHOCK HAZARD.
CAN CAUSE PERSONAL INJURY.
Always disconnect power before opening the
power supply cover.
The electronic air cleaner generates a small amount of
ozone in normal operation. During the first or second week
of operation, the amount may be higher because of sharp
edges on some of the new high voltage metal parts.
Normal use quickly dulls these edges.
The average person can detect the odor of ozone in
concentrations as low as 0.003 to 0.010 parts per million
(ppm). The electronic air cleaner contributes 0.005 to
0.010 ppm of ozone to the indoor air. The U.S. Food and
Drug Administration and Health and Welfare Canada
recommend that indoor ozone concentration does not
exceed 0.050 ppm. As a comparison, the outdoor ozone
level in major cities is sometimes as high as 0.100 ppm.
However, if desired, the ozone generated by the air
cleaner can be reduced in one of two ways:
Fig. 8. Move J5 shorting bar to reduce ozone production about 20 to 25 percent.

1. Install an activated carbon filter downstream from
the air cleaner. Make sure particles from the air filter
cannot fall into the air cleaner.
WARNING
ELECTRIC SHOCK HAZARD.
CAN CAUSE PERSONAL INJURY.
Only a trained service technician should perform
the following procedure.
2. This will reduce ozone production about 20 to 25
percent and reduce efficiency about seven to ten
percent, depending on actual airflow delivered by
the furnace blower.
a. Unplug or disconnect power supply to the air
cleaner.
b. Open the access door.
c. Remove the power box cover. See Fig. 1.
d. Locate J5 shorting bar on the power supply.
See Fig. 8. Remove the shorting bar and
reinstall on only one pin.
NOTE: The ozone will be reduced, but the shorting
bar is available for reinstallation if needed.
e. Replace the power supply cover and access
door. Turn on the power.
f. Repeat the checkout procedure before leaving
the job.
